Reynolds and Visous stress on RANS

mejahan · July 14, 2014, 18:28

Hello dear friends,

I am using RANS, SST turbulence model.
Can you please tell me how I can calculate or see the Reynolds and Viscous stresses on the post processing, including normal and shear.

Thank you for your help in advance.

Hello dear experts,

I would appreciate if anyone can help me.
I could calculate Viscous shear stress at post processing, but I do not know how to calculate Reynolds stresses. The Eddy viscosity is unexpectedly low and the flow Reynolds number is high enough to be turbulent.

Thank you for your help in advance,

Mehdi
